The PPK Ormawa BEM FMIPA UNY team conducted a workshop for the community of Prawatan Village, Jogonalan District, Klaten Regency, focusing on catfish farming using an IoT-based integrated biofloc-hydroponic system. The event featured Ahmad Ardan Ardiyanto, owner of Dewaponik and a nationally recognized hydroponic practitioner and innovator, as the main speaker.

The workshop covered topics such as biofloc pond management, hydroponic maintenance techniques, and strategies for integrating both systems to support food security and enhance the village's economy.

The UNY PPK Ormawa team, consisting of Dwi Retno Agustina, Salsabila Maryam, and Hilal Indra Soerja, introduced the application of IoT technology in the biofloc system. They presented a sensor-based "feed and care" concept that enables automatic feeding and real-time water quality monitoring. This innovation was well-received by the community, as it helps fish farmers save time and increase efficiency.

Participants practiced hydroponic seeding, learning how to grow vegetables using an environmentally friendly and space-saving hydroponic system. They also engaged in biofloc fermentation, utilizing microorganisms to maintain pond water quality, allowing catfish to grow healthily without frequent water changes. Additionally, they were trained in IoT feed and care management, with students assisting in the use of IoT devices for automatic feeding and pond monitoring, ensuring the technology's benefits were directly felt by the community.
